If I start typing a command like apt-g after hitting tab, the shell completes the command to apt-get, but for the second part of the command like install, if I enter some characters like insta, hitting tab, doesn't complete it to install.



Another example: after I enter sudo hitting tab doesn't complete anything. for example: sudo apt-ge [tab] and nothing.



I installed Ubuntu using mini iso (40MB network installer), so maybe there is a config that I missed!



I've added this code to my .bashrc but still it does not works:



if ! shopt -oq posix; then

  if [ -f /usr/share/bash-completion/bash_completion ]; then

    . /usr/share/bash-completion/bash_completion

  elif [ -f /etc/bash_completion ]; then

    . /etc/bash_completion

  fi

fi


I have also checked the permission of .bashrc and it's -rw-r--r--.



I also source the .bashrc after changes using source .bashrc to apply the changes to the new environment but still no effects.



I use xfce4-terminal so I thought it might be the terminal and not the bash.



But editing:



~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml


And changing: 



<property name="&lt;Super&gt;Tab" type="string" value="switch_window_key"/>


to:



<property name="&lt;Super&gt;Tab" type="string" value="empty"/>


Doesn't makes any difference too.

bash-completion is a set of bash scripts which enables customized completion for specific commands.


This is not just for files and directories, but also e.g. for the commands. So you type partial of commands and by hitting Tab we get a auto completion of commands.


Installation


Step 1: Install bash-completion


$ sudo apt-get install bash-completion

And some times it works if we re-installed it by the follwing command:


$ sudo apt-get install --reinstall bash-completion

Step 2: Enable bash-completion in your .bashrc file


Open your gedit ~/.bashrc and if these content doesn't exist there, add them at the end of it and save it.


# enable bash completion in interactive shells

if ! shopt -oq posix; then

  if [ -f /usr/share/bash-completion/bash_completion ]; then

    . /usr/share/bash-completion/bash_completion

  elif [ -f /etc/bash_completion ]; then

    . /etc/bash_completion

  fi

fi

Important: After changing the file you need to source your ~/.bashrc with source ~/.bashrc or reopen your Terminal. It should be fixed now.
